The invention relates to a method and to a device for removing contaminants arising during the production of aliphatic or alicyclic nitric acid esters, in particular for removing contaminants from nitrated crude nitric acid esters, which nitrated crude nitric acid esters arise during the nitration of monovalent or multivalent aliphatic or alicyclic alcohols capable of nitration, after the separation of the final nitrating acid, and to a production system for nitrating monovalent or multivalent aliphatic alcohols capable of nitration with subsequent purification of the nitrated nitric acid esters.
本发明涉及一种去除脂肪族或脂环族硝酸酯生产过程中产生的污染物的方法和装置,特别是去除硝化粗硝酸酯中污染物的方法和装置、这种硝化粗硝酸酯是在硝化能硝化的一价或多价脂肪族或脂环族醇的过程中产生的,在分离最终硝酸之后,还涉及一种硝化能硝化的一价或多价脂肪族醇并随后纯化硝化硝酸酯的生产系统。
